SURFACE CONDENSER.

pplicatio'n tiledy .Tune`8, 1926, SerialNo. 114,536, and in GermanyNovember 9, 1925.

This invention concerns a surface condenser and has for its object toprovide 'a device ot this kind in which the direction of flow of thecooling Water in the condenser can be changed.

The invention is illustrated by way of example in the accompanyingdrawing in which.

Fig. 1 is a cross section through one water chamber of a fourcompartment condenser showing the influent and effluent conduits inaccordance with the present invention,"

Fig. 2 is a plan view of the condenser,

Fig. 3 is a central longitudinal section thereof, g

Fig. 4 is a perspective view of a three coinpartment condenser with thefront cove removed, and f Figs. 5a to 5 are diagrams showing the variouscourses the cooling water ca n be made to take.

The surface condenser shown in Figs. 1 to 3 consists of a drum into thetube plates 1 and 2-0f which are drawn the tubes 3. The steam engine orturbine is connected -to the inlet connecting branch 4, and the steamenters here into the space surrounding the tubes 3. At the ends ot' thebundle of tubes are headers or wat-er boxes 5 and 6, divided.

by partitions 7, 8, and 9 into compartments l0` 11. 12,13. and 14. Theinlet pipes 15 and 16 open into one side of compartments A10 and 14respectively. The outlet pipes 17 and 18 open into the other side ofcompartments 10 and 14. The inlet pipes 15 and 16 branch froma singlepipe 19 leading from the co'ol water pump. The outlet pipes 17 and 18are `ioined to a single pipe20 which f returns the warm cooling water.The pipes 15, 16, 17, and 18`are provided' with valves 21, 22, 23, and24 respectively.

In the condenser shown in Fig. 4 the headers or water boxes 5 and 6 eachhave only one partition, 25 and 26 respectively, and the branches otthe-inlet and outlet pipes open into opposite ends of the condenser.

With either of the two condensers described there are six possible waysof running the water through the condenser as indicated in the diagramsFigs. 5a to 5f.

as 1, Fig. 3a- Valves 21`and -24 are open and valves 22 and 23 closed.Cooling Water enters compartment 10 through pipel 4 15 and flows insuccession through compartments 11, 12, 13, and'14, and out through pipe18.

-0nse f?, Fig. 5.;Valves 22 and 23 are open and valves 21 and 24 closed.Cooling water enters compartment 14 through pipe 1.6 and flows insuccession through compartments 13. 12, k 11, and 10 and out throughpipe 17.

Oase 3, Fig. r5h-Valves 22 and 24 are open and valves 21 and 23 closed.Cooling water enters compartment 14 through pipe 16 and Hows directlyacross the same and out through pipe v18.

Oase 4, Fig. 5dr-Valves 21 and 23 are open and valves 22 and 24 closed.Cooling water enters compartment 10 through pipe 15 and Hows directlyacross the same and out. through pipe 17.

Oase 5, Fig. 5ft-Valves 21 and 22 are partially" open, valve 23 fullopen, and valve 24 closed; A part of the cooling water flows throughpipe 16 into compartment 14, thence in succession through compartments13, 12, p

11. and 10, and out through pipe 17, while a part of the water iiowsthrough pipe 15l directly across compartment 10 and out througl'i pipe17.

Oase 6, Fig. 5f.-`Valves 21 and 22 are partly open, valve 24 full open,and valve 23 closed. A part of the cooling water flows through pipe 15into compartment 10, thence in succession through compartments 11, 12,13. and 14 and out through pipe 18, while a part of the water flowsthrough pipe 16 directly across compartment 14 and out through pipe 18.

These various circuits may follow each other in any desired order, ormay systematically follow in a definite sequence. 1n either casechanging current characteristics are produced which increase the coolingaction of the condenser, and above all stir up the sediment whichsettles out of the cooling water so that the same is carried out.

As is well known coarse impurities such as wood, leaves, and grass catchon the tube walls of condensers and interfere with the passage ot waterand decrease the cooling action.' These coarse impurities, as well asthe finer sediment in the tubes such as algae and the like, are stirredup and removed y the change of flow. l

Having described my invention,

I claim:

1. In a surface condenser divided into a series of compartments throughwhich cooling Water is adapted to flow in sequence, a forked coolingwater inlet pipe connected 15 site side of sai to the first. and lastcompartments of the series, a. forked outlet pipe also connected to saidfirst and last compartments, and valves in each of the forks of saidinlet and outlet pipes.

2. In a surface condenser having tubes, tube plates, and headersconnecting said tubes, partitions in said headers dividing the same intocompartments through which the cooling Water is adapted to flow insequence by way of said tubes, a forked coolin water inlet pipeconnected to one side of tie first and last compartments of the seuence, a forked outlet (pipe connected to t e oppoirst and lastcompartments,

and valves in each of the forks of said inlet and outlet ipes.

3. In a. sur ace condenser divided into a. series of compartmentsthrough which the cooling water is adapted to fiow in sequence, meansfor causing cooling water to flow through the series of compartments innormal o1' reverse direction, and means for changin the How of thecoolin Water so that 1t ows directly across the rst or last compartmentsof said series without running through the Whole series.

In testimony whereof he aflixes his signature.
